SPECIFICATION forming part of Letters Patent No. 347,543, dated August 17, 1886.

Application filed February 2, 1F86. Serial No. 190,617. (No model.)

To aZZ whom z't-mtty concern.-

Be it known that I, W1 LLLIM WrnDnMANN,

of Lawrence, in the county of Douglas andv State of Kansas, have invented a new and Improved Curtain-Fastener, of which the follow- .tain details of construction and combinations of parts, to be hereinafter more fully explained, mld fDGCClUy lQlntedout in the claims. e

Re erenoc is to be had to the accompanying drawings, forming a part of this speeiiieation, in which similar letters of reference indicate corresponding parts in all the figures.

'Figure l is a view of a portion of a curtain provided with my improved form of fastener. Fig. 2 is a viewof the under side of the fastener removed from the curtain. Fig..3 is. a view of the retaining-ring. Fig. 4 is a sectional view taken on line xa' of Fig. 1. Figs. 5, G, 7,` and 8 are detail views illustrating the construction of the jaws.

In the construction of such a fastener as is illustrated in the drawings above referred to,.

I provide an annular base-plate, A., provided with clampingears a a, and to this plate A, I Apivotally connect two jaws, B and C, by means of a pivot-bolt, Zi. Each of the jaws B and C is provided with a semicireular central recess, c, and-with manipulating-arms d (l, formed with thumb-wings c c, and each of the jaws is also Vthis washer and about the pivot l there is coiled a spring, l, the extending end of which project upward. and bear against the inner faces' of the thumb-wings e e, thus holding the jaws B and C in the position shown in Fig. 1, the

alignment of the parts being secured by means of a stop, n, formed on the plate A, and the ends of the jaws are held to the plate by overlapping ears o.

' In applying such a fastener as has been de scribed to a carriage or other form of curtain, the earsa are forced through the body ofthe curtain or passed through apertures ihr-ined therein, after which a retaining-ri ng, N, formed with apertures pp, made to register' with the lugs, is placed iu the position shown iu Fig. 4, after which the ears a. are turned down, as shown in said figure, to clamp the fastener to the curtain. The curtain isthen eut away. as

shown at o1, Figli, to permit a passage ofthe 3 button, (shown in dotted lines at i\[,)tl1ejn\vs B C being thrown apart' by pressureapplicd to the thumb-wings c c to permit the head oi' the button to pass between the jaws, so that when the .pressure is released the jaws will close about the shank of the button, as indicated in Fig. 4j

Such a fastener as has been described will hold the'eurtain against displacement by the wind, and is easily manipulated in buttoning and unbuttoning the curtain.

I am aware that a curved spring-operated catch has been pivoted within a centrally-ap ertured hollow disk having a centrally-apertured'rearface-plate; also, that two flat jaws have been pivoted at their adjacent faces to form a circular aperture to receive a knob;

also, that the outer ring of a curtainfastener hasbeen provided with clinehing-prongs that were passed through the curtains and bent broadly, es of my invention.
